To all whom it may concern .1

' Be it known that I, Janos GIBnoNs, a icitizen of the United States,residing at E WeSt Park, in the county of Cuyahoga and "State of Ohio,have invented certain new and useful Improvements in Spraying-N07,

.- a Widespread, cone-shaped, hollow mass of zles, of, which thefollowing is a specification, reference being hadtherein to theaccompanying drawing This invention relates broadly to improven'ients inspraying devices and, specifically, to spray nozzles peculiarly adaptedfor spraying trees and the like. v

One of the primary objects of thewmvention is to provide a spray nozzleof such construction. that the spraying-fluid ma v be dischargedtherefrom either in'the form of relatively short carrying powerandof'larg'e "diametra'l area, or in the form of a solid body of relativelygreater carrying, power and of relatively smaller diamotral' dimen- "Isionsh Anotherobject is to provide, insuch a construction, means forminutely controlling the flow therethrough of the spraying-final wherebythe character of the spray dis-- charged therefronrmay be accuratelyvaried. Anotherobject is to prov'ide'a structure in which thespraying-fluid maybe pro -jected through apertures in a plurality "of iflow-capacity to'change the character of the spray as it isdis'ehargedfromithc nozzle.

.by' the: flow through the apertures is bal anced; means being providedtor. controlling the flow therethrough for varying its This inventionseeks in geueralto provide for definitely controlling a relativelyrotative movement of the parts as distinguished ing actionof which isuncertain; so that,

. from an operative standpoint, my device, as

has beenfound in practical use, possesses a high degree'of eiiic encyand durabilityand 'Y'which, structurally considered, is of. great sissimplicity; I I I p r Certain other objects will'be obvious fromtheanneaed drawings, While otherswill be pointed'out in the followingdescription.

That the invention may be clearly comprchended, drawings illustratingone of the many possible utilizations of the same are hereto annexed,asa part of this disclosure;

it being manifestthat other possible utilizations' and embodiments(employing theun derlying within the spirit thereof and Within theobjects contemplated thereby.

spraycontrolling device.

Referring. to these drawings, the reference character 1 designatesnozzle-body,

preferably of the form shown, and hollow to provide a fluid-containingchamber- 2] This communicates, by an el'ongmted-chanml 3, with a port 4into-which is threaded a pipe 5 that connects with a suitable source(not shown) of spraying-fluid. The portion of the n'ozzleopposite to'the port 4 is enlarged, and thereon a cap devicc 6 is mounted. In theparticular embodiment disclosed, this includes a cap-piece 7 p1"efcr'-ably v threaded onto the nozzle-body, as shown, and provided with anenlarged opening of approximately the same diametral' dimensions as thatof the-chamber 2, The

wall of-the' outer end ofthe nozzle-body is .cut to form an annular seat9 for a spraycont'rolling and balancing diskme1nber 10. Seated upontheouterend of the nozzlebody and preferably overlapping the outer i theaperture 13 in the disk edge of the disk-member 10 is a spacingmember 11which, preferably and as shown, is of resilient material and of somewhatless internal diametral dimension than that of the opening 8 in thecap-member 7.

Retained by the cap-member 7 is a disk 12 provided with a. centralaperture 13 which is, preferably and as shown, formed withoutwardly-flared w'lls, for a purpose presently to be explained. Themember 11 maintains the disk 12 and the disk-member 10 in spacedrelation to provide an eddychamber 1 1 with which said aperture 13communicates.

The disk-member 10 is, preferably and as shown, provided with two seriesof flow passages; one comprising a primary-aperturc 15 disposed inapproximate alincment with 12 but of larger diametral dimensions thanthat aperture. as shown; the other series comprising a pluralityin thisinstance, there are three-secondary apertures 16. 17 and 18. Preferablyand as shown, the wall of the aperture 15 is straight, while those ofthe secomlary-apcrtures 16, 17 and 18 are cut at an angle to theaperture 15, and these sccondary-apertures are concentrically arrangedin relation to the primarv-anerture 15 in the disk-member 10 and alsowith the aperture 13 in the disk 12. i

It is a feature of my invention, and an important one, that thediametral or crosssectional areas of the primary-aperture 15 shall beapl'n-oximately three times that of each of the sccondary-apertures; or,other wise stated, that the aggregate of the (lian'letral dimensions ofthe secondary-apertures shall be equal to that of the primaryaperture15, as shown in Fig. By reason of this feature, the flow series ofapertures is, under certain conditions, balanced; that is to say, theflow through the primary-aperture 15 is equal to the aggregatesfiowthrough the three secondary-ape1.'tures. From this, it will be evidentthat, by varying the normal flow-capacity of the primary-afperture 15,the equalized flow, or equally-balanced capacity, is in consequencechanged. To the end that this variation may be conveniently andaccurately accomplished, and to a minute degree, and then maintained, Iprovide means adapted to control the flow of the fluid through theprimary-aperture 15. These means, in my preferred embodiment, include acontrolling-member designated, generally, by the reference-character 19and which, in this instance, is provided with an enlarged head 20 on itsinner end; with a knurled piece 21 on its outer end; and with a stem 22which is movahly guided in an opening 23 that opens into thefluid-containing chamber 2. The opening. 23 al 0 communicates with anenlarged recess 24 adaptthrough the two solution is discharged from edto receive packing in its lower por tion. Threaded into the recess is astufiingnut 26 provided with a bore 27 which. is threaded to receive athreaded portion 28 of the stem 22. By reason of the fact that thecontrolling-niember 19 is threaded into thestufling-nut 26, it has acompound r0 tative and longitudinal movement by which it is accuratelypositioned in relation to the primary-aperture 15; and, by reason of thefact that the head 20 thereof is of larger diametral dimension than thatof the prilnary-apcrture, it is adapted to be seated over and close saidprimary-apcrture when it occupies its innermost position, as shown infull lines in Fig. 3. When the primaryaperture is closed, the flow offluid is entirely through the angularly-cut apertures .16, 17 and 18,and, by reason of their position and character, they, in conjunctionwith the walls of the spacing-member 11, produce a whirling or swirlingmotion of the fluid, which, by reason of the resultant pressure. iscaused to discharge through the apcrture 13 in the disk 12. The angle ofexit of the fluid, then, will be approximately along the oblique linesAA, with a diameter equal to the laterally-extending line A. In otherwords, when the controlling-member 19 closes the primary aperture 15 inthe plate 10. the'tlow of the solution is through thesccondarv-apcrtures 16, 17 and 18' therein and. thence, into theeddy-chamber 14., The eddy-chamber is then caused to rotate or whirl byreason of its angle of entrance into the chamber.v The liquid, then inthe chamber 11. is discharged through the aperture 13 in the plate 12 inthe form of a hollow cone of a maximum angle represented by theatorementioned lines 1\-A radiating from the aperture 13. As shown, thisposition of the controlling-device with reference to the aperture 1.5permits the most widespread discharge of the spray of which the nozzleis capable. lVhen, llOWQX'Ql, the controllingdevice 19 is positionedsomewhat back and away from the aperture, as indicated in dotted linesin Fig. 3, a portion of the solution is permitted to pass through theaperture 15 as well as through the angularly-cut secondary-apertures 16,17 and 18. The passage, then, of the solution through theprimary-aperture 15 has the effect, first, of reducing the maximum angleof the spray through the aperture 13, which angle is inclicated by thelines B-B, also radiating from the aperture 13; secondly, of filling upthe center of the cone, so to speak, so that the the aperture 13 as asolid body, the diametral dimension of which is indicated by the line B;and, thirdly, of projecting the spray to a greater distance. Thereby,perfect control of the delivery of the spray and a consequent savliquidwhich is discharged into this ing thereof is accomplished. Again, whenthe controlling-device 19 is movedvbaclt to its rearmost position, asil'idicat'ed in dotted lines in Fig. 3, and is, thus, stillfarther-removed from the aperture 15, alarger quantity of the solutionis permitted to pass through the primary-aperture into the eddy-chamber14. This causes, first, a still further reduction of the angle of thespray, as indicated by the lines C C, and, secondly, a still furtherprojection of the solid cone of spray, having a diametral dimensionindicated by the line C, which effects a still greater definition in thecontrol of the spray, with a consequent greater saving of solution' thanthat where the controlling-device occupies its intermediate position ofadjustment. It will, therefore, be obvious that the positioning of thecontrolling-device 19 L. in relation to the primary-aperture l5 enablesthe operator to effect a discharge of the spray through the aperture 13at any fixed angle between-the maximum angle, indiicatedby the lines AA,and at any reduced angle, as indicated by the lines B-B,

and (I O.

The flared form of the wall ofthe aperture 13 of the plate 12 isprii'i'iarily designed to increase the distance between the face of theplate ofrthe disk 10 and the aperture 13 in order that the rotating orwhirlingmotion which is given to the solution that enters theeddy-chamber 14 through the an gularlycuit apertures 16, 17 and 18 maybe imparted to the solution which passes into the chamberll through theprin'iary-aperture 15.,

From the foregoing, it will be perceived that l: have succeeded indevising a spray-- nozzle which is well adapted to achieve the severalobjects and ends 111 View.
